What can you do already wrong in a measuring cup? Emsa how it's done: The "brim" the top of the cup is completely circumferentially, rather than only where they are needed. Result: After Dishwasher transition that thing is always full of water and Spülresten, and partly the brim is so thin that simply can not get there with a cloth. Consequently, the thing is constantly dirty. Not true where one measures (yes, this may be the measuring cup), but still annoying's halt.
